To all 'whommay concern: I

Be it known that I, RoscorJ S. yE.\'llrmNnR, a citizen ofthe UnitedStates, residing at Philadelphia, in the county of Philadelphia 4and`State of '.Pennsylvania, have invented certain. newv and useful Tool-(perating-` Machines, lowing` iS a specification. f

@ne object of my invention is to provide `a machine of; the above typewhich Willbe 'of which the `folotsiinple construction and which canbeeasily. manipulated.

VAnother object is to provide my improved machine with means whereby thetool can be quickly and easily raised and lowered without changingtable.

located centrally between the side surfaces thereof, and this recess 3extends vertically and intersects theupper surface t oi! the base (seeFigs. 1, 2 and 5).

. Furthermore,.this recess has its opposite surfaces 5 arranged parallelto form a slide way for the saw-carrying bearing. This b earingcomprisesa block 6 which has opposite plane suifaces?, designed to `slidably litagainst the surfaces 5 of the slideway, and a Harige 8 which is designedto embrace the rear face of the `base 2;

An extension 9 is provided on said block, and this extension forms thelower half of the journal for carrying a shaft 10 which supports thecircular saw 11. A bearing cap 12 forms the upper half of the journalearing and is seeuredto the extension 9 'by bolts13. j A; plate 14 hastwo opposite faces 15 which registerwith the faces 7 of the block 6 andalso slide within the slideway provided by the recess. A stud 16 has oneend rigidly secured within the plate, and the other end designed tofreely pass through a hole 17 in the block 6.' This latter mentioned endof the stud 16wis provided with screw-threads and is of such length asto project beyond the rear surface of. the block 6 `(see Fig. 3).

A. handle 18 has a threaded opening which is designed to engage thethreaded end of the stud 16 and bear against the rear face of the block6 so that a rotation of said handle in one direction will serve to movethe plate 14 and block 6 toward each other and to bind the `flange S ofthe block 6 against the rear face of the base 2 and` will also-serve tobind plate 14 against thel forward face of the base 2, thusI firmlysecuring theblock and plate tothe base.

The upper end of the plate 14 has a pin 20 designed to enter a cavity 21in a forward overhung portion 22 of the extension 9 (see Figs. 3 and 5).The block 6 has an internally `screw-threaded hole 23 which is arrangedvertically and is designed to receive the upper threaded end of avertical post 2e,

the latter being rotatably mounted and seated within thelower end of therecess 3 (see ally operative shaft 2T, the latterl being jouringvertically.

The shaft '27 at its outer endis )rovided y w iere yv with a crank arm'2S and handle 29, the post 24 canf be rotated through the mediuni ofsaid gears and shaft The shaft l0 has a collar O` which is rigidlysecured thereto and forms the abutment 'for one face or the saw 11 andanut 31 screwed onto the threaded end 32 or the sha'litlO,` serves tosecurely bind the saw to the collar 30.

The opposite end ing pulley 33 secured thereto which is rotatableby abelt 34. rlhis belt has its upper run 35 engaged by a take-up roller orpulley 36,\the latter being rotatable on an arm 37 which is pivotallymounted onla bracket 38 secured to the base 2 by a bolt 39. The arm 37lis acted upon by a coiled spring 40 which, in the present instance, isconnected with the standard 1. The function of this roller 36 is to takeup slack which occurs due to vertical adjustment er the saiv carryingshaft 10 as will hereinafter be more fully explained.

The base Q, adjacent to its upper portion, has tvvo extensions 4l and42. These extensions at their loiver ends are provided with bosses 43and 44 respectively. These bosses are provided with threaded openings45,'

either of which can be engaged by a threadu ed rod 46 which is securedto a hand lever 47 y and is designed to protect 'through a mental slot48 in depending portions 49 olf supporting arms 56 for the Work table51. These arms 50 have holes 52 therein designed to be engaged by pivotpins 53 which are secured within the vupper portions of the extensions41 and 42, the axes oit these pivot pins 53 being in a differentvertical plane from the axes of the threaded openings 45 above referredto7 thus permitting the table 51 to tilt or turn on the pivot pins 53Without greatly changing the relative position, with respect to the saw,oi? an open ing 54 in a block 55 through which the sanT extends (seeFig. 3). i

This block 55 is readily removable 'from the table proper and rests uponledges 56 formed Within said table top so that the top ol" the block 55is substantially flush with the top of the table 51.

ln operation, when it is desired to change the position of the sanT withrespect to the top of the Work table 51. the handle 18 is loosened torelieve the binding action between the plate 14 and the block 6. Theshaft 27 is then rotated through the medium of the handle 29, and sincethe post 24 cannot move vertically, the effect of the screwthreads onthe post and the internal screwgear 25 i olf the shaft has a driv` .lsaid shaft 2,

heightrof the sanv Vhas 18 can be turned 6 and plate 14 to After theproper been attained, the handle to again clamp the block the'base 2 andthe machine isi'eady for operation.

It will be noted that according to the arrangement of the beltillustrated, if the saW is lowered, the spring-40 will serve to pulltheftakeaip roller downwardly and thereby takeup any slack in the run 35of the belt. On the other hand, it' the saiv is moved upwardly, thespring 40 Will yieldin proportion to the upivard movement and therebyprevent undue strain on the belt.

lVhen it is desired to tilt the -table7 the hand lever 47 can be readilyloosened and afterthetable top has. been rocked on the pivot pins 53',thc hand lever 47 can be again tightened to secure the table in theadjusted position. Y i 1 I preferably provide lingers 57 at the eX-tremetop of the base 2 which act as additional supports for the tablewhen the latter is in a horizontal position and which also act as stopsto permit the return of the table to a horizontal position.

l providea rail 55a on the top of the Work table 51 and provide thisrail with two longitudinally slotted `arms 56a. Clamping bolts 57 aredesignedto extend through the table 51 and through the slots Within thearms 56a so that the rail 55 may be moved toward or from the san7 l1.

In Figs.` 6 to S inclusive, I'have shown a form of my invention Whichcan be made extremely small and is` ivell adapted for household use,manual training schools,` or other `places Where a serviceable littleniachiiie is desired. VIn this form of my in vention7 l eliminate themeans for raising' and lowering the circular saw such for eX-- ampletasthe elements includingthepost 24, gears 25, 26, and handle Q9. f

Referring to Figs. 6, 7, and 8, 5S represents a base which provides avertical slide-` Way 59` for a block 60, and a plate61, said bloclrandplateA being provided with flanges 62 and 63 Which respectively embraceopposite -aces of the base 58. The plate 61 has a stud; 640i similarconstruction to the stud 16 above described, and said stud` 64 extendsthrough the block 60Landat its outer thread ed end is provided with aWing nut 65 which serves to bind the plate 61 and block 60 to the base58.

The block 60 has an extension 66 which forms a bearing for a shaft 67,saidsha'lt having a collar 68- thereon against which abuts a circularsaw 69. A nut 70 ismount-` ed on the threadedend 710i the shaft 67`collar 68.`

the upper face of the Connection between and is designed to clamp thesaw againstthe The opposite end ofthe shaftli'l` is provided with apulley 72. A 'work table 73 has arms 74 which are designed to rock uponpivot pins 75 which project from opposite extensions 76 and 77 of thebase 58.

A threaded stud 791is Vmountedin the exand from the saw 69. This railhas bolts 85 which extend therethrough and which ride Within slots 86formed within said table adjacent opposite ends thereof.

The rail 84 acts as a guide for the edge of the material to be sawed. Ipreferably insert a screw 87 through the plate `6l. and block 60, andwhile this screw forms a loose the block 60 and Vthe Y plate 6l, itserves to prevent undesirable jamming between said plate and block, sothat when the wing nut is turned, the plate 6l and block 60 will movesmoothly toward or from each other.

In this form of my invention7 the saw 69 can be adjusted vertically byhand after the wing nut 65 has been loosened, and the table 73 can beturned on the pivot pins 75 by loosening the wing nut 80 and can besecured in a tilted position by tightening on said Wing nut 80. Y l

While I have described my invention as taking a particular form, it willbe understood that the various parts of my invention may be changedwithout departing from the spirit thereof, and hence I do not limitmyself to the precise construction set forth; but consider that l am atliberty to make such changes and alterations as fairly come Within thescope of the appended claims. l
